I have a Redboard that I would like to connect a temperature sensor to it that measures temperature based on resistance. Can the analog inputs measure resistance or can they only read voltage?

they read voltage... but if you make a voltage divider (e.g. resistor R1 connected to +3.3V, the other side of the resistor connected to the temperarature sensor AND the analog input, the other side of the temperature connected to GND), you can measure a proxy for the temperature resistance. R1 would be around the same resistance as the temperature sensor.
